InDesign not exporting booklet as pdf

[stephen.a]

Good morning, community!

I am trying to export a booklet that is 72 pages long. Yesterday, it exported without a problem. However, today, I get the following dialogue boxes:

  Do you know what could be causing this problem? Is it InDesign or potentially my printer's software?

Thank you!

That is not an export; it is the print dialog. AFAIK, you'd need to print to postscript and distill to get a PDF this way.

My suggestion is to export a proper PDF and use the booklet feature in Acrobat to print it.
